6349-1. Specifications
IS200t_EE(OM53D77E)
Oil viscosity (0W-20 is explained here as an example): • The 0W in 0W-20 indicates the characteristic of the oil which allows cold startability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil containers to help
you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designation by
American Petroleum Institute (API).
Center portion: “SAE 0W-20”
means the SAE viscosity grade.
Lower portion: “Resource-Conserv-
ing” means that the oil has fuel-saving
and environmental protection capa-
bilities.
ILSAC Certification Mark
The International Lubricant Specifi-
cation Advisory Committee (ILSAC)
Certification Mark is displayed on
the front of the container.
